Develop a model to describe the cycling of matter and … For the most accurate results, be sure students have access to the Internet. For links to additional information about sea level change, visit the NASA Earthdata Sea Level Change Data Resources page. Figure 2: Combined observed (black line) and projected sea level rise for two future sea level rise scenarios. Using Mathematics and Computational Thinking, CC.5.G.2 Graph points on the coordinate plane to solve real-world and mathematical problems. They can use the questions above as a guide for what they should share out. What was different? NASA Wavelength. Additionally, we have tide gauges on Earth to ground-truth (locally validate) our satellite measurements. Locally, citizens are making observations – and already seeing the impacts of sea level rise on their communities. Clearly, sea level rise is something that is already affecting people and will continue to do so. The new Sea Level Change Data Pathfinder delves into many of the datasets scientists use to study the status of global and regional sea level change. These sensors profile ocean expansion, the thermosteric sea-level rise that, as we have seen, is a consequence of ocean heat absorption. meter sea level rise should not be seen as an immediate concern. Science Briefs The Great Ice Meltdown and Rising Seas: Lessons for Tomorrow. Sea level rise is not just an academic concern for NASA satellites and scientists. HS-ESS3-5: Analyze geoscience data and the results from global climate models to make an evidence-based forecast of the current rate of global or regional climate change and associated future impacts to Earth's systems. "Every year, every decade, we're remaking the climate and raising sea levels higher and higher." Published November 5, 2020. For over 20 years, satellite altimeters have measured the sea surface height of our ever-changing oceans. GRACE data provide important information about the amount of sea level rise caused by melting ice and changes in rainfall that add water to the oceans. Monthly Deviation in Sea Ice Extent from 1979-2017, Data Collections: Earth System Data Explorer, Locating Data & Imagery for Student Investigations, Opening Datasets from MND Data Visualization Tool in Excel, Guide to Using NASA Worldview in the Classroom, Using NASA Earth Observations (NEO) in 10 Easy Steps, Instructional Strategies for the Earth Science Classroom, Student Activity Sheet Sea Level Rise (pdf). "Every year, every decade, we're remaking the climate and raising sea levels higher and higher." The mission is a collaboration between NASA and the European Space Agency. NASA’s Climate Change and Global Warming • Sea Level Lesson Plans: Graphing Sea Level Slopes and Surface Currents Data Jigsaw: Exploring Sea Level Rise with Others Stability and Change: Monitoring Sea Level Creating Your Own Sea Surface Height Model Connect the Spheres: Earth Systems Interactions Lessons in Sea Level Rise For ground-based geodetic stations like SLR and DORIS, the exact position of the station must be known. Analyze and interpret data from fossils to provide evidence of the organisms and the environments in which they lived long ago. Explain why melting land ice causes sea levels to rise, but melting sea ice does not. As accumulating atmospheric greenhouse gases lead to further climate warming, sea level rise will accelerate, endangering coastal communities by more frequent flooding, exacerbated beach erosion, and saltwater penetration into streams and aquifers. What was similar within resources? Because preconceived notions may influence the perception of fact, be sure to have students do the math first, then attempt to draw scientific conclusions. Even NASA is concerned about some of its facilities that are located in low-lying areas. It does this for the entire Earth every 10 days, studying how global sea level is changing over time. How might change in the Hydrosphere affect changes in the other parts of the Earth System? Since 1880, the global sea level has risen 8 inches; by 2100, it is projected to rise another 1 to 4 feet. Global sea level is rising approximately 0.13 inches (3.3 millimeters) a year. Step 4: After each member had a chance to share their summary, together the groups need to answer: Data Jigsaw: Exploring Sea Level Rise with Others, For over 20 years, satellite altimeters have measured the sea surface height of our ever-changing oceans. Earth’s surface may seem motionless most of the time, but an array of measurements show that natural and human-caused processes cause coastal land to rise and fall. But before we get into that, let’s understand the main contributors to sea level rise: Let’s take a closer look at global sea levels. Melting mountain glaciers - Glaciers are bodies of ice on land that are constantly moving, carving paths through mountains and rock. Sea Level Rise NASA Resources for Grades 3 to 5 3rd- 5th grade NGSS related to Sea Level Rise: 3-LS4-1. Current news and data streams about global warming and climate change from NASA. The spacecraft was equipped with two altimeters and a microwave radiometer, which corrected for the effects of water vapor on radar signal transmission; other instruments ensured precision tracking of the satellite’s orbital position [Mitchum et al. Thermal expansion of water - Consider that our oceans absorb over 90 percent of the heat trapped by greenhouse gasses in Earth’s atmosphere. What do you still need clarification on from within your resource? (All resources are found in the Google Slide provided.) The Jason-3 satellite uses radio waves and other instruments to measure the height of the ocean's surface – also known as sea level. NASA Watches Sea Level Rise from Space, and its Centers' Windows › more sea level news. NASA is studying the Earth's ice and water to better understand how sea level rise might affect us all. The graphs depict how much the sea ice concentration moved above or below the long-term average. That's 30 per cent more than when NASA launched its first satellite mission to measure ocean heights in 1992. (CNN) – NASA is launching a new satellite into space, that will monitor global sea levels. When scientists refer to changes in sea level, they are referring to changes in the height of the mean sea surface relative to a mean sea level defined by the earth’s geoid. Melting polar ice caps - Think of our north and south polar regions. You may be asking yourself, how do we know sea levels are rising? See All Cryosphere Mini Lessons. These are all great questions! The questions involved in this activity refer to interactive online graphs. The same logic can be applied to the sea level budget: When each factor that affects sea level is added together, this estimate should match the sea level that scientists observe. This sequencing will provide them with independent data from which to make statements. "Every year, every decade, we're remaking the climate and raising sea levels … Represent real world and mathematical problems by graphing points in the first quadrant of the coordinate plane, and interpret coordinate values of points in the. Compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land. The mission is a collaboration between NASA and the European Space Agency. The mission is a collaboration between NASA and the European Space Agency. They estimate that over the past 140 years, global mean sea level has risen 21 to 24 centimeters (8 to 9 inches). With two-thirds of its infrastructure and assets situated on the coast, the agency has first-hand experience with the effects of rising waters. NASA keeps track of sea level change and its causes from space. Construct an argument with evidence that in a particular habitat some organisms can survive well, some However, the global average of 3 millimeters of sea level rise per year is increasing and the rate that it’s increasing is speeding up. Figure 2: Combined observed (black line) and projected sea level rise for two future sea level rise scenarios. Warming temperatures cause mountain glaciers and polar ice caps to melt, thereby increasing the volume of water in the oceans. "Sea level is continuing to rise and we can't stop measuring it," says Josh Willis, the mission's project scientist at NASA's Jet Propulsion Laboratory. There are 5 regions of focus: • central Pacific • central Atlantic • southeast Asia • US east coast • US west coast The span of time shown in each visualization is about 10 months. The mission is a collaboration between NASA and the European Space Agency. The advent of gravimetric measurements with the twin GRACE satellites in 2002, along with more recent deployment of floating Argo sensors, opened the way to “closure” of the sea level budget—that is, when the sum of observed ocean mass and density changes equals total sea level change [Leuliette and Willis, 2011]. Since 1992 NASA, NOAA and European partners have been tracking global ocean surface topography with joint ocean altimeter satellite missions from an orbit 1,336 km above the ocean surface. Emissions Could Add 15 Inches to 2100 Sea Level Rise, NASA-Led Study Finds. Watch this video for some illustrations of these facts: Also check out the Climate Time Machine for Sea Level to see what impact a 1 meter to 6-meter rise in sea level will have on the coastal US and other areas of the world. This website, presented by NASA’s Global Precipitation Measurement (GPM) mission, provides students and educators with resources to learn about First, the melting of ice sheets and glaciers on land are adding more water to the oceans. The South Pacific island nation of Kiribati saw a 2.6 millimeter rise in sea level between 1992 and 2010. Sea level rise is caused primarily by two factors related to global warming: the added water from melting ice sheets and glaciers and the expansion of seawater as it warms. Complete the "Lessons in Sea-Level Rise" activity. (They do not plot total sea ice concentration.). The basics of sea level rise, expressed in everyday terms, and what it means for those on the coast. Earth Headlines This reviewed collection of NASA Earth and space science resources is for educators of all levels: K-12, higher education and informal science education. Portal origin URL: Emissions Could Add 15 Inches to 2100 Sea Level Rise, NASA-Led Study Finds ... Greenland and Antarctica’s ice sheets could together contribute more than 15 inches of global sea level rise by 2100. This record began with TOPEX/Poseidon, followed by Jason-1 and the Ocean Surface Topography Mission on Jason-2, and will be continued by Jason-3. In the meantime, we need to be prepared for the impact encroaching seas will have on our coastal communities and water supplies. Sea level rise is the increase of the average global sea level. MS-ESS3-3: Apply scientific principles to design a method for monitoring and minimizing a human impact on the environment. ... Students explore the effects of ice sheets on global sea level using NASA data. What was the most important part of the resource? The Sentinel-6 Michael Freilich satellite launched Saturday as the next generation of spacecraft keeping an eye on global sea level. "That was a problem," said Frederikse. Some of the Argo data had been corrected by Argo quality-control teams, although uncorrected data also were used. If we can control our contributions to the rise in greenhouse gases in Earth’s atmosphere, we can perhaps level out the warming of the Earth system and eventually stabilize our sea levels. 3-LS4-3. Until now, however, the sea level budget has fallen short of the observed sea level rise. The spacecrafts' radar altimeters measure the precise distance between the satellite and sea surface. However, if Internet access is not available for students, consider projecting one set of graphs for the whole class to consult and appointing one student to mouse over appropriate points. Alex S. Gardner, research scientist and member of NASA's Sea Level Change Team. How does it affect us? Students need to fill in the other three parts as group members shares. Well, a couple of ways. HS-ESS2-2: Analyze geoscience data to make the claim that one change to Earth's surface can create feedbacks that cause changes to other Earth systems. (The authors say that temperature measurements from the floats, unlike salinity measurements, show few instances of data drift. It doesn’t mean that seas are higher by the same amount everywhere. Environment. GRACE measures changes in water mass, including terrestrial storage in the form of groundwater, rivers, snow and ice, and mass changes within the ocean itself, as well as the movement of water between land and ocean. The mission is a collaboration between NASA and the European Space Agency. Credit -. Take a look at this video for some great visuals and further explanation of how phenomena such as the Gulf Stream affect local sea level heights. There are many reasons why the ocean surface is lumpy. Coastal systems are especially vulnerable to climate change impacts such as ocean acidification, changes in ocean temperatures and sea level rise. Do I have to be concerned about it in my lifetime? Looking at the average height of the sea across the planet, we see that in the last 25 years global sea level has been rising an average of 0.13 inches (3.3 mm) per year. All three contributors to sea level rise can be attributed to the warming of the Earth system. Warming temperatures cause mountain glaciers and polar ice caps to … When water heats up, its molecules become more energetic, causing the water to expand and take up more room, so that accounts for about a third of sea level rise. Newsletter Sign up for our Newsletter Get the latest information on sea level science, news, data, and newest features of the NASA Sea Level Web Portal. It is, however, meant to assess the sensitivity of local sea level rise to melting of polar regions. This is a collection of visualizations of ocean flows created in support of NASA's 2020 sea level rise campaign. Alternately, print hard copies of the graphs for students to mark up and estimate using their graph-reading skills. By Vivien Gornitz — June 2012. The deployment of floating sensors across the world’s oceans, known as the Argo project, reached a critical mass in 2007, with some 3,000 of the devices set adrift to measure temperature and salinity in the ocean’s upper 2,000 meters[Leuliette and Willis, 2011]. Explore standards-aligned lessons from NASA-JPL in science, technology, engineering and math for students for grades K-12. Once in orbit, each satellite will collect sea level measurements "down to the centimeter for 90% of the world’s oceans," according to NASA. “Sea level rise” – we hear that phrase, but what does it mean, really? Credit - NASA. For links to additional information about sea level change, visit the NASA Earthdata Sea Level Change Data Resources page. Find climate resources in the collection at the following link, which can be filtered by audience, topic, instructional strategy and more. They then compare the sea level rise trends to those in a graph of temperature data. Students address following questions in the space for each resource. Simulations of sea-level rise and contribution from the cryosphere Simulate sea-level rise and how it is affected by changes in Earth's icy regions Model the evolution of sea level over the entire Earth, and understand the contribution of glaciers and polar ice caps to its rise or decline in a changing climate. The Earth's oceans have soaked up the vast majority of the extra heat, and about one quarter of the extra carbon dioxide, that humans have generated by burning fossil fuels. 2010]. The color range for this visualization is -7 cm to +7 cm … Together with our international and interagency partners, we’re monitoring the causes of sea level rise with high accuracy and precision. Melting land ice, however, contributes to about one-third of sea level rise. Melting ice has already caused sea levels to rise by about 8 inches since 1880, and the trend is accelerating. This website, presented by NASA’s Global Precipitation Measurement (GPM) mission, provides students and educators with resources to learn about Projected global climate model (GCM) changes through time are joined to the observed historical data. When do we see the most change in sea level? Sea level is not constant everywhere. One recent estimate, covering 1955 through 2010 [Levitus et al., 2012], relied upon historical data and more modern readings from the World Ocean Database 2009, additional data from NOAA through 2010, and Argo data that became available in early 2011. Sea Level Rise Hits Home at NASA. The top line shows the Arctic; the middle shows Antarctica; and the third shows the global, combined total. All three contributors to sea level rise can be attributed to the warming of the Earth system. In fact, in some areas, such as the west coast of the US, sea level has actually dropped slightly … for now. In this lesson, students will conduct labs investigate the drivers of climate change, including adding carbon dioxide and other greenhouse gases to the atmosphere, sea level rise, and the effect of decreasing sea ice on temperatures. Published November 5, 2020. Projected global climate model (GCM) changes through time are joined to the observed historical data. Sea Level Rise NASA Resources for Grades 6- 8 6th through 8th grade NGSS related to Sea Level Rise: MS-LS2-3. HS-ESS2-4: Use a model to describe how variations in the flow of energy into and out of Earth’s systems result in changes in climate. This is accomplished through the use of the Terrestrial Reference Frame . In this lesson, students will conduct labs investigate the drivers of climate change, including adding carbon dioxide and other greenhouse gases to the atmosphere, sea level rise, and the effect of decreasing sea ice on temperatures. What do you want to research more about this topic. More recent efforts, however, led to reports of closure for more extended periods, including a NOAA report covering 2005 to 2013 ("The Budget of Recent Global Sea Level Rise, 2005-2013," by Eric Leuliette).
